- To all whom it may concern.-

Be it known that I, HENRY A. GoLL, a citi-. zen of the United States, residing at No. 323 'VVest Van Buren street, in the city of Chicage, in the county of Cook and State of Illinois, have invented a new and useful Improvement for Angular lhrottle-Valves, of which the following is a specification.

l My invention is a valve-pipe or valve-chest having inner projections which are provided with parts of the bearings for the valve-shaft. These projections are further provided with seats which meet againstthe bearings and face in opposite directions for valves such as described. According to the construction and arrangement of the seats on these projections the shape, form, and area of the opening in the valve-pipe is produced, which, afterhangjthe, throttle-valve in the pipe by means zoofavalvesha'ft, and said shaft resting with i-ts bearings 1!] the mentioned parts of bearljn'gs on the projections, constitute the passages in said pipe.

My invention consists in supplying the projections in the valve-pipe with flat seats which meet against the bearings and face in a slantin'g opposite direction;. further, in supplying 'the wings of angular throttle-valves with fiat seats that meet against the bearings and correspond with the seats on the projections in such a manner that the seats on the valve fbearfluid-tight against the seats on the projections and prevent all escape of fluids of any kind when the valve has closed the pasrangements of the seats on the projections.

The seats on these projections can be arranged in such a manner that the valve, when hung in the pipe by meansof the valve-shaft her'einafter descrihed,'and fitted tOthe seats on the projections, the passages being of unequal area, 8 0., fluids of any kind acting toward the valvehpause the valve tobe auto matic, a non-return valve permitting fluids to go through the pipe only in one direction- 6 toward D, &c. The seats on these project ons can further be arranged in such a maner that the valve, when hung in the pipe, to, as mentioned above, ceases to be a nonreturn valve. The valve is then controlled by means of the valve-shaft from the outside of the pipe at will and the valve controls the passages and the fluids. The seats beingarranged as hereinafter described, the passages being closed by means of the valve, the, the seats on the projections forming joints with the seats on the valve, the pressure-area on the seated sides of the wings is reduced by .as much as the area of the seats on these of the seats on the'projcctionrflhe passages,

when opened by means of the valve, &c., remain open, asthen the pressure-area is the same toward the valve in every direction, and tluids of any kind can go in either direction 1) toward S or S toward D, the.

In order to give a better understanding of my invention, 1 have marked corresponding parts with similar letters, and of which I will now givea detailed descrlptiomrefcrence being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in Wl1lOl1 Figure l is a front view of an angular valve hung diametrically in a longitudinal section of a part of a cylindrical pipe having inner projections, also showing the hearings for the valve-shaft, glands or screws, stuffing-boxes, packing, as ordinarily in use, applied to the wings of the valve held against the seats, &c., by means of eoverplates,bolts,or screws, &c. l igs2and3 are sect-ions of cylindrical pipes or chests having inner projections, showing seats on the projections, hearings, passages,

c. Fig. 4 isa sectional side view of an-an-- gular valve in a longitudinal section of a part of a cylindrical pipe havinginner projections,

showing seats on the projections, bearings, the valve hung diametrically in the section of pipe, the valve in solid lines when the valve has closed the passages, in dotted lines when the valve has opened the passages, (to. Fig.

5 is aside view of an angular valve, showing I braces with which the valves wings are strengthened should they require it, the. Fig. 6 is a cross-section of the valve in position slightly modified by having its leaves more nearly in one plane.

13, Figs. 1, 2, 3, and 4, are sections of a cylindrical pipe or valve-chest having internal meeting projections or ribs M and Z. The pipe and the ribs are provided at the junctions of the ribs with the bearings G g for the, journals onthe valve-shaft. The

planes of these ribs M and Z, on which arethe seats hereinafter described, face in op valve has closed the passages,

posite directions and are slanting with the .sides (upper and lower, Fig. 4) of the pipe.

The object of having the planes on these ribs slanting is that the ribs may have the bearings G for the purpose hereinafter mentioned, and that the valve may be enabled to open cylindrical pipe to the fullest extent, so that steam, water, or fluids of any kind may 'go through the pipe freely and with the least obstruction in the valve-chest. The valve being hung in the pipe, as hereinafter described, in order to prevent steam, water, 850., fromgoi'ng through the pipe and passages, the'seats on the valve-wings must he fitted to the seats on the ribs and the journals on the shaft fitted to the bearingsin such a manner that the seat; on the valve form joints with the seats on the ribs, and likewise the journals on the shaft form joints with the bearingswhen the The ribs M and Z are provided with flat seats W and T, likewise with parts of the bearings G. The seats 7 and '1 face in 0pposite directions,-meet with the hearings in 5 line with the pivots, and are arranged in planes which are inclined to each other at an obtusefangle adapted to form joints and fit the seats L and O on the valve-wings. The bearings are adapted to form joints and fit the valve-shaft journals when the passages 1 1 and 2 are closed by means of the valve.

- means of trunnions or a valve-shaft R in such a manner that the valve with its shaft is en abled to swing. Said shait has its bearings at the junctions of the ribs, partly in the sides ofthe pipe 9 and partly in the pipe on the ribs G, Figs. 2, 3, and 4:. In order to place the valve in the pipe the valve and the shaft can be made in sections or the pipe'can be made in sections, or-both, according to the adaptability. v

The valve-shaft R has plates or washers U abutting against the endsof the bearings-to D toward prevent the valve from moving sidewise.

These are larger than the diameter, of the bear-in gs and are held to their places by means of screws or glands K by known methods.

The shaft B, Fig. 1, is extended from c,

, passes through the washers U, packing N,

and gland K far enough, so that a key, Wrench,

. or other means, according to the adaptability,

may be applied, with which to control the valve from the outside of the pipe at will.

The braces V are for the purpose of strength- ,ening the valve-wings should they require it.

In using packing sueh'as is ordinarily in use on the valve-wings the valve has coverplates 0,.through which pass bolts or screws,

by which means the packing P is held against the seats L and O. Said cover-plates must be smaller than the seats L and O on the valve and the seats NV and T on the ribs, in order to allow only the packing to be between the seats on the valve and the seats on the ribs when the passages are closed by means of the valve. A pipe or valve-chest having internal meeting-ribs provided with seats and bearf ings, &c., as herein described, according to the construction and arrangement of the seats- VV and T, Will. cause a swinging valve, as de-' scribed, when hung in said pipe, and the seats on the valve being fitted to the seats on the ribs, and-the journals on the shaft to the bearings, either to be an automatic non-return- 1 valve, a relief, or check-'valvtg, easily con- 'trolled from-the outside of thepipe at will, so as to allow fluids to go or "prevent fluids from going in either direction-S toward D or The valve, to open the passages automati cally to a stronger suction at one end of the pipe 1): or to a -stronger pressure of fluids of any kind coming from the'opposi'te chi of the pipe S and to close the passages by m'eansof its own weight as soon as saidsuction or press u're has ceased, must swing with its shaft in the bearings freely. The bearings should be about horizontal, the wings must be of unequ'al'weight, and the seats N and T on the ribs must be constructed and arranged in such a manner that when the passages are closed by means of the valve the inner closing edge ofthe seat W will cause the passage} 1 to have a larger; area than the area of thempassage 2 and the seat T combined.

The ribs M and Z and the seats thereon meet against the valve-Shaft. Thebearings,

as shown on the drawings, are placed diametrically in said pipe B, which is not essential, for in apipe or valve-chest having the internal meeting ribs, as described, the operation would be the same should the bear-.

ings be toward one side of the pipe. It is necessary, however, to construct and arrange the seats, passages,-&c., as described. As

shown-on the drawings-the seats on the ribs are of about an'eve'n width. The seat edges are of about an even distance from the inner sides of the pipe. When the valve is fitted to said seats and hung as shown, and the outer of the passage 1 and the [0 levers, springs, '&c.an automatic non-re tur i'valve which will allow steam, water, &c., to go in but one direction-S toward Dwill prevent anything from going in the opposite directions-D toward Swhether the pipe is ['5 in.a slanting, horizontal, or vertical position,

unless the" valve is prevented from so doing by means applied to the valve-shaft, as mentioned, 650. there is at S, or a stronger pressure of steam,

water, or fluids of any kind coming from S than there is at D toward the wings H and A causes the wing H with its iucreasedarea to turn toward D and the center of the pipe. The

wing A, being overpowered by the wing H,- z5 will turn toward S and the center of the pipe,

thus opening the two passages land 2, and the fluids will pass through those passages 1 and 2 and finally out at D. As soon as the mentioned suction or pressure has ceasedthe o'valve will again close those passages 1 and 2 by means of its own weight, seats, 850., for the purpose mentioned above.

To control the valve from the outside of the pipe, that steam, water, &c., may go or be prevented from going in either direction- 1) toward S or Stoward Dat will, by means of the valve-shaft, &c., the inner closing edge of the seat V must be constructed and arranged in such a manner that the'passage 1 0' has a smaller area than the area of the passage and the seat T combined, and the inner closing edge of the seat T must be constructed and arranged in sucha manner that the passage 2 has a smaller area thanthe area seat 7' combined, as shown in Fig. 6.

The'pipes, the seats, the passages, &c., being constructed as described, the valve being fitted to said seats and hungin the pipe by means of the valve-shaft, which in such a case canbein any position, subject to the conditions above stated, and the passages being closed by means of the valve,a pressure from either end of the pipe D or S of steam,

5 5 water, 850., would cause the valve toattach itself 'firmer to the seats XV and T and prevent steam, water, 850., from going through the passages, for there is superior force exerted upon the non-seated sides of the valvewings, corresponding to the area of the seats \V and T on the ribs M and Z. This is also the area which only is required to be overcome to relieve the valve from the seats W andT and to open the passages l and 2.

hen the passages are open, steam, water,

&c., can go in either direction-toward S or S 1) towardll-ns then the pressure on both A stronger suction at D than sides of the wings is the same, no matter what. position the valve and pipe is in.
